I am on all fours on my marital bed and my stepdaughter, Chloe has just scrawled the word WHORE across my ass, using the buttplug shoved in my rectum as the O. Not for the first time, I wonder, “How has this happened?”

Chloe reaches for and grips the plug with her fingers. She tugs on it once more, stretching my puckered star. I whimper with shame. It comes out with a faint pop, and I feel surprisingly empty as she places it on the dressing table. She has already stepped into the harness and now I watch her drizzle lube onto the shaft of the girlcock and rub it up and down. It smears and coats the cock as she slowly wanks it. The mattress sags a little when she climbs back onto the bed. She positions herself behind me, dragging the head of the girlcock along my slit. I grip the sheets, waiting for her.

Her fingers reach up and grab my hair. She presses the head of the girlcock against my star. Before I have time to even open my mouth to protest, she yanks hard on my hair, snapping my head back. She presses her hips forward at the same time and pushes the girlcock into my ass.

Whatever words I was trying to form come out instead as a strangled scream. There is pain. I can hear myself whimpering from a distance. Chloe slams the girlcock into my virgin ass with enthusiasm, telling me I am a dirty little whore as she thrusts inside me again and again.

I glance sideways and watch what is happening in the dressing table mirror. Chloe is pulling my hair with one hand and steadying herself by placing the other hand at the small of my back. She has a look of intense concentration on her face, as if she were being graded on a test.

The only sounds are my laboured breathing and the rhythmical slap of Chloe’s thighs against my ass. Despite the pain, despite the humiliation, the pleasure rises inside me. I feel completely owned by Chloe. She can do whatever she wants to me, and I will enjoy it because it brings her pleasure.

“That’s it Mummy. You are such a fucking whore,” she growls. “You’ll do anything I tell you. You’re nothing but a cock hungry whore.”

Her words make me blush but I press my ass back into her, wanting her to take me, to fuck me, to make me hers. I have submitted to her fully.

I am pulled away from these thoughts of pleasure and submission by a loud, incessant ringing of the doorbell. Chloe pulls out, and I slump, frustrated, onto the bed.

“Stay there, Mummy,” she orders. I kneel on the bed on all fours as she unfastens and steps out of the girlcock and puts her skirt and blouse back on, though not bothering with underwear and heads downstairs..

I wait, like she told me, wondering who it is and contemplating what they would say if they saw me. I hear her walk downstairs and open the front door. There are voices and giggling. I think I recognise Ashley’s voice and another deeper voice.

I hear the thump of footsteps on the stairs as they all traipse up. I’m suddenly aware of my nakedness but it is too late to worry about that now. I am facing the door and I watch it open, as if in slow-motion. Chloe enters, followed by Ashley and a tall, young, black man.

The man stands in the doorway looking a little bemused. Ashley nudges him forward into the room and Chloe closes the door. I remain kneeling on the bed and face them. Ashley smirks but the young man just stares. He looks from Ashley to Chloe and back to me. Chloe sidles up to him and runs her hand along his arm whilst leaning up and kissing his neck. Ashley does the same on the other side. Both girls press themselves against him.

“So, Mummy.” Chloe giggles as she turns to face me. I watch her run her hand over his crotch. “Do you think it’s true what they say about black men?”

“Oh, it is,” Ashley interjects, her fingers also running over his crotch and Chloe’s fingers. “I can vouch for him.”

He is incredibly good-looking. His skin is the colour of my morning espresso, rich and dark. His eyes are shining, and when he smiles, his teeth are a brilliant white. I slowly shake my head.

“I’ve no idea, Chloe. I… I… I’ve never seen one.”

“This is Jacob, Mummy.” Chloe nudges him forward some more until he is standing at the end of the bed. “If you’re a good girl, maybe you’ll find out.”

“Hello, Jacob.” I flush as I whisper his name.

From the corner of my eye, I see Ashley move behind me. Almost immediately, she laughs and I remember the writing on my ass cheeks.

“Oh she really is such a whore, Clo.”

Chloe meanwhile is undressing Jacob. She stands behind him and tugs his fleece up over his head. His white singlet shows off his physique. He is toned and muscular. Chloe runs her fingers over his crotch and I can feel my tongue slither out to moisten my lips as I watch the bulge grow.

Ashley slides her hands over my marked ass before leaning forward and dragging her tongue along my slit. She scoops up my juices and I moan with unbridled lust. I focus my gaze on Chloe’s fingers as they unbutton Jacob’s jeans. She presses into Jacob’s back and I watch my stepdaughter kissing the young man’s neck. She opens the fly and pushes his jeans down his thighs.

She rubs his cock through his boxer shorts. Her fingers grip the hardening shaft and Jacob sighs with pleasure.

“Do you like his cock, Mummy?”

She pulls on the elasticated waistband and tugs his shorts down to expose him. My eyes go wide. He is big. Fuck, is he big. He’s definitely bigger than the girlcock that she’s just used to ravage my ass. It’s magnificent.

I nod, unable to speak. He’s not fully hard yet Chloe can’t fit her fingers around it. Her hand looks so small when she rubs his shaft, making him swell and bringing him to full hardness. Ashley’s tongue continues to lap and lick at my slit and I groan.

I groan, with need for Jacob’s cock or with the pleasure of Ashley’s tongue on my pussy, I neither know nor care. I am nothing but a bitch in heat. A whore. Chloe has made me a whore.

“Show him how you suck cock like a good little whore, Mummy.”

My cheeks flush red. I nod and lean forward, opening my mouth, my tongue is out, desperate to lick and suck. Ashley shuffles forward, trying to keep her tongue in me as I lean forward and drag my tongue up his shaft. It feels like velvet. It’s so much better than the fake cock Chloe wore earlier. It pulses. I can feel his heart pump his blood into his cock as it swells and grows. I roll my face against it.

Then I open my mouth and swallow the head. I suck gently, feeling a sense of pride as I hear his breath huff through his nose. His almost needy whimpered “Fuck” makes me drip on Ashley’s face.

“That’s it whore. Swallow his cock.”

I open my mouth and try to swallow him. I hear Chloe tell him to fuck my face and not hold back.

Chloe’s hand caresses my hair. I gaze up at them. Jacob is staring at me, not quite believing what he is doing. Chloe smirks as she pushes on the back of my head. She pushes my head forward onto Jacob’s cock.

Under Chloe’s insistence, Jacob begins to thrust harder. “That’s it,” she encourages him. “Fuck the whore. Make her gag.”

I let him fuck my face. My brain turns to mush. All I can think about is being a good girl. A good girl for Jacob. A good girl for Ashley. A good girl for Chloe. I drool on Jacob’s cock. My eyes glaze over. Chloe tells me I am just a set of fuck holes. I try to agree but can’t talk with a mouth full of cock. Ashley pushes two fingers into my pussy. They use me as a toy. As a fucktoy.

Ashley curls and uncurls her fingers inside me. She taps on my soft sponge spot that makes me whimper with need. Her thumb mashes my clit as she fucks me and Jacob fucks my mouth.

Jacob's scent fills my nostrils. My nose is buried in his black pubic curls. Ashley's fingers slam in and out, her knuckles stretching my wet velvet walls.

And then Ashley slips away. She leaves my pussy dripping and empty and edged.

I try to complain, try to beg her to come back but Jacob's cock fills my mouth and I'm unable to speak.

Then Chloe whispers to Jacob. She tells him to fuck me. To take my fuckholes. She tells him that I’m a dirty whore who needs to be bred.

He pulls his cock out of my mouth and I whimper in needy desperation. I watch Chloe as Jacob gets behind me. Chloe is standing holding up her phone. She is filming me. I want to say No. I want to tell her to stop but Jacob shoves his big hard cock inside me and all thoughts of protestations disappear.

“Beg for it, Mummy,” Chloe calls. “Tell him how much you need his big hard cock.”

And to my shame, I do just that. I press my ass back, encouraging him to fill me deeper, to fuck me harder.

I beg.

“Give me your big hard cock, Jacob,” I beg.

“Fuck me like the dirty whore I am,” I howl.

I have no shame. I move my ass back, welcoming the young man’s cock in my cheating pussy.

My orgasm is building.

I beg in breathless, panting whimpers. “Fuck me. Fuck me harder. I’m going to cum.”

His cock slams into me. His fingers grip my hips and pull me onto his cock as he slams into me. Deeper. Harder. Faster. He fucks me with the exuberance of youth and a total disregard for me. I’m a piece of meat for him, being goaded on by my stepdaughter.

And then, through the fog of lust, I realise Chloe is talking while filming.

“Daddy, I’ve just got home from school and walked in on Mummy having sex in your bed.”

I watch as she turns the phone around to show Derek what I'm up to. As Jacob enthusiastically slams his cock into me from behind, I can see Derek’s face on the screen. I look into his eyes as he watches Jacob cry out, “You fucking whore” as he cums inside me. He watches as his wife is filled with another man’s cum.

“Chloe, No,” I cry, attempting to get off the bed and get to Chloe. To turn off the phone. To try to explain to Derek that it isn’t my fault.

I struggle free from Jacob, giving Derek a good look at the virile, hard cock that had just been in his wife. I clamber off the bed, trying to get to the phone to explain that it's not my fault.

“I’ve got to go, Daddy,” Chloe cries, tears running down her cheeks. “I’m so sorry but I had to tell you.”

She hangs up and faces me, her fake tears quickly replaced by a triumphant grin.

“Fuck,” Jacob whimpers, slumping back against the wall. His cock softens as he staggers back. Ashley hands him his clothes and the two of them slip out of the bedroom, leaving me alone with Chloe.

“Why?”

“Daddy needs to know that he married a whore.”

“I’ll have to tell him that you made me. This is all your doing.”

She laughs. Then she gives me an almost pitiful look.

“You’re really going to tell him that after you seduced and slept with his sixteen year old daughter and bought her sex toys and that I made you have sex with another man?”

The enormity of what I have done finally sinks into my cum-addled brain.

Which is worse? I think. I know the answer. She’s right. I can’t tell him about her. About the changing rooms, the videos, about her and Ashley using me. I know how it would look. No one would believe me. Two innocent sixteen year old girls corrupted by an adult. Not just any adult, but the stepmother of one of the girls.

“But why would you do this, Chloe?” I can feel tears running down my cheeks.

“You really don’t get it do you?”

I shake my head in bewilderment.

“I always loved the Snow White story when I was growing up.” She stares into my eyes. “And do you know why?”

I stare, confused. What has Snow White got to do with anything?

“At the end, Snow White makes the wicked stepmother dance in red hot shoes until she drops down dead.”

I swallow, waiting for the coup de grace. She doesn’t disappoint.

“So after Daddy comes home and throws you out for being a whore, he will bring my real Mummy back. And then we will all live happily ever after.”
